ABSTRACT
The role of Newcastle disease virus and neoadjuvant therapy was assessed in 84 cases of breast cancer T1-4N0-2M0 (2005-2008). Combined use of the virus vaccine and chemotherapy (group A), therapy with the vaccine alone (group B) and chemotherapy regimen identical with that used in group A (group C) were compared. Histological pattern of tumor and stage were identified using expression of receptors of steroid hormones, oncoproteins Her2/neu and p53 as well as proliferation activity (marker Ki-67) before and after therapy. It was shown that the efficiency and safety of Newcastle disease virus (apathogenic strain La-Sotha) met specific immuno- and neoadjuvant therapy standards.

The data on 25 cases of histologically verified bronchioloalveolar carcinoma and papillary adenocarcinoma are discussed. Reliable differential diagnostic cytological features of both diseases were established using a statistical, program and fine-needle biopsy findings. Statistical analysis data pointed to the sets of cytological features: "serial pattern--clear cell boundaries" and "serial pattern--presence of macrovacuoles" as a major factor of accuracy of bronchiolo-alveolar carcinoma and papillary adenocarcinoma diagnosis. These cytological features may be used for reliable diagnosis of the diseases.

Cytological differential diagnostic features of bronchiolo-alveolar carcinoma and papillary adenocarcinoma are established basing on the material of needle biopsies by means of Statistica program. It is found that the strongest influence on the cytological diagnosis of these two tumors is associated with the following pairs of cytological features: lane--clear-cut cell borders and lane--the presence of macrovacuoles.

This review concerns the development and progression of one of the forms of peripheral lung cancer--bronchiolo-alveolar carcinoma (BAC). The study is based on the comparison of roentgenological, histological, immunohistochemical examinations and results of surgical treatment of 482 patients with this tumor. Morphological and clinical variants of BAC are defined. It is confirmed that their biological behavior may vary within the forms and differ from common adenocarcinoma. A close correlation exists between clinicoroentgenological picture and histological form of BAC.

Clinicomorphological analysis was performed in 12 cases of atypical adenomatous hyperplasia of the lung (AAH). This is the proliferative lesion consisting of atypical epithelial cells along the alveolar septa which are found incidentally during pathologic examination of the lung resected because of cancer. We studied morphological and biological characteristics of AAH cells including cytodifferentiation, proliferative activity, tumor-suppressor genes. Our review of the studies of AAH revealed that AAH is alveolar intraepithelial dysplasia and a precursor of lung adenocarcinoma. AAH is an important lesion corresponding to a step in carcinogenesis for peripheral lung adenocarcinomas.

Results of combined treatment of 113 patients with colon carcinoma receiving a single irradiation (7.5 Gy) before the operation were analysed. The single irradiation was well tolerated by all the patients without complications during the operation and in the postoperative period. It is found at the ultrastructural level that from 70 to 85% of the cells in the tumors removed were irreversibly damaged.
